GI 3.2 to 3.7 Development

You don't have access to browser functionaloty from script, good thing you have not.

One thing you could do is register a confirm function to the BEFOREUNLOAD event of GI. Then the user gets a confirm dialog whether to leave the page or not, like it is done in the GI IDE.

In your project settings "onLoad Script":

jsx3.gui.Event.subscribe(jsx3.gui.Event.BEFOREUNLOAD, checkExit);

In your code:

function checkExit() {

arguments[0].returnValue = 'your confirm message';

};
